look up any word, like bukkake:
It's BETTER then an orgasm. Over 9000 times better.
Guy 1: Yeah, so I totally nailed that one chick last night.

Guy 2: Ah yeah, I heard, she's a screamer when she orgasms.

Guy 1: Oh, that wasn't a mere orgasm, that was a sexgasm. Most incredible thing I've ever seen.
